Review of some custodial sentences which are for a period of more than one year is provided for. The grounds, time and procedure for review are set out in the Act. 

If the juvenile has appealed his or her sentence there can be no review of it until the appeal is completed. 

If the Director of Youth does not bring the juvenile to court for the review of his or her sentence, the court may order him or her to do so. 

No juvenile shall remain in a juvenile facility after he or she reaches the age of eighteen years, unless the court is sure that remaining in the facility would be in the best interests of him or her and would not affect the safety of others. If this is not the case, then as mentioned earlier, the juvenile would be transferred to an adult facility.
There can be no appeal of a review of a sentence.
